Abstract (en)

[origin: EP3590832A1] The invention is related to a control system 10 for controlling the pitch of rotor blades 1b, 1c of a multi-blade rotor 1a in a rotary-wing aircraft 1, and, more particularly, to the actuator fork 20b, 100 and the actuator arms 20a, 200 of the control system 10 for controlling the pitch of rotor blades 1b, 1c. The control system 10 may include an actuator arm 20a, 200 and an actuator fork 20b, 100. The actuator arm 20a, 200 is mounted in a manner that allows rotation around an actuator arm rotation axis 125 on the actuator arm pivot bearing 30a, 300 between two attachment points. The actuator fork 20b, 100 provides two separate supports 110, 120 for the two attachment points. One of the supports 120 is located in an overarching flange 130 that at least partially encompasses the actuator arm 20a, 200.
